I've been trying out field weakening on my baserunner and I noticed that after enabling it I sometimes get this fault (1-3 Current Sensor Calibration). The bike still seems to operate normally after this, and I think that it only occurs when I'm really pushing the bike hard (like full throttle), but I'm not certain. I can't get the fault to occur when FW is disabled. ASI docs says this under "how to fix" for this fault:
Eliminate possible magnetic fields.
If the fault doesn’t clear after rebooting and removing possible magnetic field effects, contact ASI for support.

It also says this about field weakening:
"Excessive field weakening can reduce the quality of back EMF, reducing sensorless driveability."

I have the field weakening current set to 8A, is this "excessive"? It also happened at 5A max FW current. Any suggestions? Safe to ignore this fault?
 
8A doesn't seem like a lot, but what components are you running? is it the motor in your build link in the signature?

This era of All Axle motors can come with a number of issues... do you notice any other strange things with your motor?

Yes it's the link in my signature, nothing else strange with the motor. Grin said that I can try to move the baserunner and/or wires to try and get the controller away from any EMF from the wires, but I can also ignore the fault. What other issues are there with the All Axle? I haven't had any other issues over the 2500 Km I've ridden on it so far. I also thought it was a controller issue and not motor.
